Welcome Jessica!

Jessica Ka Yi Chiu has joined the Department of Geoscience and Petroleum at Norwegian University of Science and Technology (NTNU) to undertake a 4-year PhD-project in the field of Engineering Geology and Rock Mechanics. The main supervisor is Charlie Chunlin Li (Norwegian University of Science and Technology) and co-supervisors are Ole Jakob Mengshoel (Norwegian University of Science and Technology, Department of Computer Science), Karl Gunnar Holter (Norwegian University of Science and Technology and Norwegian Geotechnical Institute) and Vidar Kveldsvik (Norwegian Geotechnical Institute).
Jessica’s project “Optimising rock support design: installation and mapping in hard rock based on automated joint detection and artificial intelligence (machine learning and evolutionary computation)” aims to investigate the possibility of designing rock support and perform objective rock mass mapping based on automated joint mapping of scanned profiles through AI methods. The project’s ultimate goals are to streamline the process, increase the quality, and possibly reduce the amount of rock support compared to current practices.
Jessica has BSc. in Earth Sciences from the University of Hong Kong, and MSc. in Geosciences from University of Oslo.
Welcome Jessica!

Hvor kommer sanden i verdens største delta fra?

Hvor kommer sanden i verdens største delta fra? Hvordan kan vite det hvor den kommer fra? Dette er sentrale spørsmål for Trond Svånå Harstad i arbeidet med sin nylig avlagte doktorgrad «Single-mineral provenance method development with a case study from the Late Traissc Barents Shelf», ved NTNU, institutt for geovitenskap og petroleum.

I avhandlingen har han studert mineraler i sandsteiner fra det enorme deltaet som utgjør Snadd og De Geerdalen formasjonene av Midt- og Sentrias alder, i Barentshavet og på Svalbard. Harstad har utviklet/videreutviklet to metoder for bedre å identifisere kilden til sanden, en metode basert på mineralet Cr-spinel og en metode basert på formene til mineralet zirkon. Han forteller at Cr-spinel viste å være et veldig godt egnet mineral til å identifisere forskjellen på bergarter, da de har helt ulik kjemi. For å gjenkjenne og klassifisere formen på zirkonkorn i fotografier brukte han kunstig intelligens, en innfallsvinkel som er ny innen dette fagfeltet. Arbeidet ble utført som et samarbeid mellom NTNU og Norges Geologiske Undersøkelse (NGU), mens feltarbeidet og prøveinnsamlingen ble gjort i samarbeid med Petroleumsdirektoratet og Sintef.

Og hvor kommer sanden fra? I begynnelsen av deltaet kommer mesteparten av sanden fra Uralfjellenes forløper Uralidene. På slutten av avsettingshistorien er Taimyrhalvøya i det nordlige Sibir sannsynligvis kilden for mesteparten av sanden.

Welcome Lewaa!

Lewaa Hmadeh has joined the Department of Geoscience and Petroleum at the Norwegian University of Science and Technology (NTNU) to undertake a 3-year PhD-project in the field of Drilling Engineering . The main supervisor is Behzad Elahifar (Associate Professor, Department of Geoscience and Petroleum – Norwegian University of Science and Technology, NTNU) and the co-supervisor is Sigbjørn Sangesland (Professor, Department of Geoscience and Petroleum – Norwegian University of Science and Technology, NTNU). Lewaa’s research “Applications of bismuth alloys in well completion and well plugging» aims to evaluate and test bismuth as an alternative sealing material. The research will propose and evaluate applications of bismuth alloys in well completion and P&A, and will model the interaction between bismuth alloy and steel/cement/cap rock formation. At advanced stages, the project will integrate digitalization in the planning of Plugging and Abandonment operations. This research is part of SFI SWIPA which is an initiative that aims to obtain a scientific understanding of permanent well barriers and allocate for improved well barrier design methodologies

Lewaa has a B.E. in Petroleum Engineering from the Lebanese American University, and pursued his MSc. in Drilling Engineering at the Norwegian University of Science and Technology.

Welcome Lewaa!

Welcome Mehman!

Mehman Ahmadli has joined the Department of Geoscience and Petroleum at Norwegian University of Science and Technology (NTNU) to undertake a 3-year PhD-project in the field of Subsea Technology. The main supervisor is Tor Berge Gjersvik (Norwegian University of Science and Technology) and as co-supervisors are Sigbjørn Sangesland (Norwegian University of Science and Technology) and Rory MacKenzie (TOTAL). Mehman’s project “Valves and materials – design concepts for simplifications” will investigate new possibilities for valves and actuators assuming all-electric control system and exploit alternative designs (valve types, materials, and placements) exploiting possibilities from rearrangement of equipment that are proposed to enable low-cost subsea field development.

Mehman has B.Eng. and MSc. in Petroleum Engineering from Heriot-Watt University and Norwegian University of Science and Technology.

Welcome Mehman!
